Chemical reactions involve electrons and where they move (if they move).
Metal atoms (or elements) usually give away their outer shell electrons in reactions to become stabilised (creating positive ions). Non-metal atoms (or elements) usually gain electrons in order to become stable (negative ions). Some reactions involve covalent bonds, metallic bonds, ionic bonds etc., but at the base (no pun intended :D) of most chemical reactions it's just a matter of electrons moving around between atoms.
Hope it helps!
Answer:
Protons= 17, Electrons= 17, Neutrons= 18
Explanation:
The atomic number (Z) corresponds to the number of electrons that is equal to the number of protons (17). The mass number (A) corresponds to the sum of protons and neutrons present in the nucleus (35). Therefore, we calculate the number of neutrons: 35-17 = 18
When molecular hydrogen (H2) and oxygen (O2) are combined and allowed to react together, energy is released and the molecules of hydrogen and oxygen can combine to form either water or hydrogen peroxide.
